Web Components

Web Components are a set of standards currently being produced by Google engineers as a W3C specification that allow for the creation of reusable widgets or components in web documents and web applications. The intention behind them is to bring component-based software engineering to the World Wide Web. The components model allows for encapsulation and interoperability of individual HTML elements. Support for Web Components is present in Chrome and Opera and is in Firefox (with a manual configuration change). Microsoft's Internet Explorer has not implemented any Web Components specifications yet. Web Components consist of 4 main elements: Custom Elements, Shadow DOM, HTML Imports and HTML Templates.

This article shows how to save the names and URLs of open Firefox tabs in a plain text file with FoxyTab, a Featured Extension. I tested it in the latest Firefox Quantum release (61.0.1 on this article's publication date), both 32-bit and 64-bit, and in Windows 7, 8.1, and 10 — all worked perfectly.

Build a website from the ground up by first learning the fundamentals of HTML5 and CSS3, the two popular programming languages used to present content online. HTML deals with fonts, colors, graphics, and hyperlinks, while CSS describes how HTML elements are to be displayed.

Every business owner understands the significance of online customer reviews and the impact it can have on sales and revenues. With technology advancing at such a rapid pace, getting online reviews has never been easier, especially when many regions around the world are already using the Internet.

Before we dive into the marketing strategies involved with creating an effective homepage, it’s crucial that EE members know what a homepage is. In essence, a homepage is the introductory, or default page, of a website that typically highlights the site’s table of contents.

In this article you will learn how to create a free basic website on Bitbucket, a git service provider. Polymer creates dynamic HTML components, which allow more flexibility than static HTML. This tutorial uses Ubuntu Linux but can also be done on Windows.

Article update on 27-July-2018: The bad news is that with the official discontinuation on 16-July-2018 by AE Creations of the Send Tab URLs add-on, this Experts Exchange article is deprecated. The good news is that there's an excellent alternative called FoxyTab, discussed in my new EE article:

Firefox seemed to slow down recently and it occurred to me that I had many open tabs — ultimately, I would find out that three-quarters of them were Experts Exchange tabs! :)

So I decided to go on a hunt for a tool that would capture the names and URLs of all open tabs and put them in a plain text file. That way I could close the tabs, thereby improving Firefox's performance, but still have a record of them in case I want to find one and resurrect it.

This Firefox add-on creates a list with the names and URLs of all open tabs in the current Firefox window. It has the ability to email the list or copy the list to the clipboard. I've never tried the email feature, as it (1) doesn't interest me and (2) is limited to 30 tabs. The copy-to-clipboard feature can handle an unlimited number of tabs — you'll see below why this is important to me. If anyone tries the email feature, please post a comment with your results.

I started using Send Tab URLs with Firefox 32.0.1 and am using it on the latest version as of this article's publication — 34.0.5. The website says that it supports English, Chinese (Simplified), Dutch, German, Hebrew, Italian, Korean, Polish, Portuguese (Brazil), and Swedish, but I have used it only with the one language I know. If anyone tries it with a language besides English, please post a comment with your results.

After installing the add-on, you will have two ways to invoke it:

Open menu (the three horizontal bars in the upper right of the toolbar):

File>Send Tab URLs...:

When you run it via either of those techniques, Send Tab URLs offers three styles for the list of URLs — Plain list, Numbered, Bulleted:

I wanted to see how bad things were, so I went with Numbered. When it is done processing, which is lightning fast, it displays a pop-up in the system tray/notification area:

With the list on the clipboard, you may paste it wherever you want, such as Notepad.

Now for my stunning results — 908 open tabs! Here's what the first line of the text file looks like:

I then went on a massive clean-up campaign, closing almost 800 tabs. My next run of Send Tab URLs showed this:

From Send Tab URLs (135 links)

Yes, Firefox performance improved!

Being a plain text file, it is easy to insert comments documenting the situation, such as this in my 908-link file:

Firefox is getting sluggish, so I decided to save this
list and close all EE tabs and maybe some others. I
want to get way down from the 908 currently open.

I put the date/time in the file name and will keep all of the text files for future reference (they are small — the 908-link one is just 140KB; the 135-link one, just 18KB).

Hi Marc,
Thanks for joining Experts Exchange today and reading my article. Yes, AE Creations said in their blog that Send Tab URLs is their least-used extension, and they have the data to back it up (copied here under "Fair Use"):

5,786 average daily users between July 2016 and July 2017, compared to 8,354 for Panic Button and 35,962 for Clippings.

Because of this, they also said that they've "decided to discontinue development of Send Tab URLs, and focus on Clippings and Panic Button."

Seems that you have the hard data saying that Send Tab URLs is the least-used extension, but, for me, it's the only one from AE Creations that I use (never even heard of Clippings or Panic Button). I run Send Tab URLs often on many machines...even published an article about it that may interest you..."How to save the names and URLs of open Firefox tabs in a plain text file":

Of course, I'm extremely disappointed that you are discontinuing it. But I thank you for the more-than-a-year that I had with it, and for providing such an excellent tool at no cost. That said, I'd be happy to pay for it, and I suspect that many of your 5,000+ daily users would be, too. I urge you to reconsider your decision to discontinue it and, instead, rewrite it as a WebExtension for Firefox 57, perhaps even charging a fair price for it. Thanks, Joe

They haven't responded to my comment (or the comments from others), so it's safe to say that I did not persuade them to reconsider their decision to discontinue it.

Thank you for providing the link to the 57-compatible Export Tabs URLs by AL and letting us know that it works fine.

I made this because I wanted to get e-mail with a attached csv file so I'd would be able to import user input into a MS Excel template, but I also wanted to register/save all inputs from each day in a file on the server.

1st - It creates a temp CSV file that is attached to the e-mail to me with the comma separated inputs.

2nd - If there hasen't been any inputs from that day it make a new CSV file on server or if there has been inputs from that day they are appended to the existing file.

After spending tons of time reading up on the subject i made this code script, that will let you get the user input sent to you as a E-mail with a CSV file attachment.

The PHP code as it is at the moment will make two CSV files.
One that is stored on the server that holds all inputs from that day $fp = fopen("file".date("d-m-y").".csv",'a');
and the one that is e- mailed to the chosen e-mail $FileName = $formdata.date("d-m-y-h:i:s").".csv";

I'm working on getting it to send the inputs in the E-mail message also.

Hope you can use it, modify it etc.
Brian A.

Update!!!
I'm currently testing a new version that also sends the user a message that displays the input in a mail with a table layout, It just lacking a bit of fine tuning, but is looking good.

I bet that many of you that tried to make a web form been battling with malformed char set, that's my last hurdle in one of the mail headers.
